How To Obtain Bis Certification For Lithium-ion Batteries In India?

About Lithium-ion batteries

Lithium-ion batteries are rechargeable energy storage devices that have gained widespread popularity due to their high energy density and long lifespan. Lithium-ion batteries are often used in rechargeable energy storage systems, electric vehicles, and portable electronic devices. The cathode, anode, electrolyte, and separator are the key elements of a lithium-ion battery.

Lithium-ion batteries are a high energy density, which enables a longer runtime compared to other rechargeable batteries. Additionally, they can hold their charge for a long time when not in use because of the low self-discharge rate. Due to the absence of harmful heavy metals like lead or cadmium, they are also eco-friendly.

BIS Certification for the lithium-ion battery

The Bureau of Indian Standards (BIS) is a national certification body in India that sets standards and certifies products, including lithium-ion batteries, to ensure their safety, performance, and quality. In India, BIS certification is mandatory for all lithium-ion batteries used in electronic devices and appliances.

The BIS certification process involves a series of tests and evaluations to ensure that the batteries meet specified standards. These tests include:

• Charge/discharge testing: To evaluate the battery's ability to store and release energy, and assess its capacity and voltage.
• Safety test: These tests evaluate the safety of the battery in normal and abnormal operating conditions, this includes tests such as overcharge, over-discharge, short circuit, and thermal shock.
• Performance test: This test measures the battery's capacity, voltage, and charging/discharging time.
• Environmental test: This test measure how well the battery performs in different humidity and temperature conditions.
• Charging/discharging profile testing: This test examines the battery's charging and discharging behavior to make sure it complies with the requirements.
• Cycle life testing: This test establishes how many charges and discharges the battery can endure before noticeably degrading.
• Aging test: This test determines the battery's longevity and the rate of deterioration over time.
• Impact testing: This test assesses the battery's safety and stability in the event of physical damage.

Once the battery passes all the tests and evaluations, the manufacturer can apply for BIS certification for battery. If the certification is granted, the manufacturer can then use the BIS mark on their products, indicating that they have met the relevant standards and are certified for use in India.

How to get BIS registration for lithium-ion batteries?

The process for obtaining BIS registration for lithium-ion batteries in India is as follows:

• Submit an application: The first step is to submit an application to the BIS, along with all required documentation, such as product specifications, test reports, and the manufacturer's information.
• Testing and evaluation: The next step is for the battery to undergo testing and evaluation at a BIS-approved laboratory. The laboratory will conduct various tests to assess the battery's safety, performance, and quality, as per the BIS standards.
• Inspection of manufacturing facility: Once the tests are complete, a BIS inspector will visit the battery's manufacturing facility to verify that the battery is being manufactured as per the specified standards and guidelines.
• Grant of license: If the battery passes all the tests and the manufacturing facility inspection, the BIS will grant a license and issue a BIS certificate. The manufacturer can then use the BIS mark on their products to indicate that they have been certified and are compliant with the relevant standards.
• Renewal of license: The BIS license and certificate are valid for a specified period, usually two years. The manufacturer must renew their license and certificate before the expiry date to continue using the BIS mark on their products.

Documents Required for BIS Registration of Lithium-Ion batteries

The following are some of the common documents required for BIS registration of a lithium-ion cell in India:

• Filled Application form
• Product specifications
• Test reports
• Manufacturing process details
• Manufacturer's information
• Financial statements
• Declaration of compliance
• ISO certificate
• Trade Mark Certificate

Conclusion

In conclusion, lithium-ion batteries have a wide range of applications due to their high energy density, long lifespan, and low self-discharge rate. BIS certification is important for ensuring the safety and quality of lithium-ion batteries used in electronic devices and appliances in India. Before registration, BIS involves a series of tests and evaluations to ensure that the batteries meet specified standards. The manufacturer can apply for BIS certification once the battery passes all inspections and tests. If the certification is obtained, the manufacturer can use the BIS mark to identify their goods as having complied with the necessary requirements and being approved for use in India.
